An Iranian long-range shore-to-sea missile called Qader (Capable) is launched during Velayat-90 war game on Sea of Oman's shore near the Strait of Hormuz in southern Iran January 2, 2012.

Iran has threatened to destroy US military bases across the Middle East and target Israel within minutes of being attacked, Iranian media reported on Wednesday, as Revolutionary Guards extended test-firing of ballistic missiles into a third day.

Israel has hinted it may attack Iran if diplomacy fails to secure a halt to its disputed nuclear energy program. The United States also has mooted military action as a last-resort option but has frequently nudged the Israelis to give time for intensified economic sanctions to work against Iran.

"These bases are all in range of our missiles, and the occupied lands (Israel) are also good targets for us," Amir Ali Haji Zadeh, commander of the Revolutionary Guards aerospace division, was quoted by Fars news agency as saying.

Haji Zadeh said 35 US bases were within reach of Iran's ballistic missiles, the most advanced of which commanders have said could hit targets 2,000 km (1,300 miles) away.

"We have thought of measures to set up bases and deploy missiles to destroy all these bases in the early minutes after an attack," he added.

It was not clear where Haji Zadeh got his figures on US bases in the region. US military facilities in the Middle East are located in Bahrain, Qatar, the United Arab Emirates, Kuwait and Turkey, and it has around 10 bases further afield in Afghanistan and Kyrgyzstan.

Scepticism

Defense analysts are often skeptical about what they describe as exaggerated military assertions by Iran and say the country's military capability would be no match for sophisticated US defense systems.

Iran has upped its fiery anti-West rhetoric in response to the launch on Sunday of a total European Union embargo on buying Iranian crude oil - the latest calibrated increase in sanctions aimed at pushing Tehran into curbing nuclear activity.

Revolutionary Guards commanders have also threatened to block the Strait of Hormuz, through which more than a third of the world's seaborne oil trade passes out of the Gulf, in response to the increasingly harsh sanctions.

Major powers have said they would tolerate no obstruction of commercial traffic through the Strait, and the United States maintains a formidable naval presence in the Gulf region.

Iran accused the West of disrupting global energy supplies and creating regional instability and says its forces can dominate the vital waterway to provide security.

"The policy of the Islamic Republic is based on maintaining security in the Persian Gulf and the Strait of Hormuz for all ships and oil tankers," Iranian English-language state Press TV quoted the chairman of parliament's national security and foreign policy committee, Alaeddin Boroujerdi, as saying.

The United States and its allies accuse Iran of using its nuclear program to covertly develop all the components required to produce nuclear weapons, accusations the Iranian officials have repeatedly denied.

The world's No. 5 oil exporter maintains that it is enriching uranium for nuclear fuel only to generate more energy for a rapidly growing population.
